Biomimetic stealth materials are artificial materials with similar functions to biological materials imitated through the study of biological camouflage properties and the simulation of the compositional structure and properties of biological camouflage performance carriers as well as their control and change characteristics.Plants,as a common background,are studied and learnt from the microstructure and transpiration of plants to provide a better integration of stealth materials into the environment.Many animals have been evolving for a long time and possess innate camouflage ability,which provides a reference idea for visible light/infrared stealth materials,radar stealth materials and smart stealth materials.This paper mainly introduces the research on stealth materials designed according to biological camouflage mechanisms,including stealth materials inspired by plant structures,stealth materials inspired by plant transpiration,infrared stealth materials inspired by animal structures,radar stealth materials,and intelligent stealth materials.
